Kittitas County Public Works led a planning project to develop a river corridor assessment that identifies and prioritizes habitat restoration actions for salmonid species in a four mile long reach of the Yakima River south of Ellensburg. Initially this project involved only the Hansen Pits levee setback, but in developing the floodplain restoration project there, it became apparent that a larger area needed to be assessed prior to fully developing any levee relocation. Upstream of Hansen Pits is the Jeffries Levee and the Schaake property owned by the US Bureau of Reclamation (USBR). The Jeffries Levee was found to be a significant influence on the river system within the reach, and the Schaake property is slated for levee relocation and the reconnection of the floodplain and side channels to the Yakima River. Coordination between this proposal and the USBR work may increase the benefits of both projects. The river corridor assessment begins at the Jeffries Levee upstream of the Hansen Pits and extends downstream to Ringer Loop Road. The assessment identifies priority locations within the project reach for improvements in riverine and floodplain habitat that will result in significant increase in the quantity, diversity, and productivity of habitats over a range of flows for various life stages of listed and non-listed salmonids. Target species include steelhead, spring Chinook and Coho salmon. The final report and companion technical memos summarize existing conditions in the project reach; explain the selection criteria and methodology used to identify and prioritize projects; identify and prioritize potential projects; and develop conceptual designs and cost estimates for priority projects. The total project cost was higher than that estimated during application as the consultant cost estimate was higher than expected. The application's estimate was based on similar work conducted on a much smaller stream and it didn't take into account the much greater size and complexity of the Yakima R floodplain and, thus the greater amount of time necessary to gather data and interact with landowners.
